IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent No. 190,525, dated May 8, 1877;

application filed February 1 2, 1871.

To all lwhom it may concern:

Be it known that I, GUsTAVUs E. TAFT, of Whitinsville, in the county of Worcester and State of Massachusetts, haveinvented Improvements in Spinnin g-Machines, ofwhich the following is a specification This invention relates to improvements in spinniiigmachines, and has reference to the combination, with a spindle and a bobbinliolder attached thereto, of a locking device to prevent the removal ofthe holder' from the top of the spindle when the bobbin is lifted or doii'ed.

This invention is specially applicable to ring-spinning frames and mules.

Figure 1 represents, in elevation, a spindle provided with one form of holder and bobbin in accordance with this invention. Fig. 2 is a modification thereof; Fig. 3, a top view of the holder shown in Fig. 2. Fig. 4 is another modification Figs. 5 and 6, bobbins of different shapes; Fig. 7, a detail of the upper end of the spindle shown in Fig. 2.

In that class of machines for spinning yarn wherein the bobbins are fitted to tapering spindles, and caused to move therewith by frictional adhesion of the surfaces in contact, the bobbins, when the spindles run at high speed, are lifted toward the end of the spindle more or less by its vibrations, thereby causing the top of the bobbin to wabble or shake. The bobbin may fall or again settle down to its place, only to 'be again lifted. This lifting and consequent loosening of the tit between the tapering surfaces permits the bobbin to fall behind the spindle and receive fewer rotations, which tends to produce slacktwisted yarn, and the slack portions, being weaker, are liable to break either in spinning or subsequent processes, and, further, the variations of the position of the bobbin upon the spindle causes the latter to Wear its bearings unevenly. When these ordinary bobbins are changed from one spindle to another it is very difficult to place all the bobbins in line upon the spindles, and to prevent overwinding the bobbins are commonly made longer than the traverse of the ring-rail. The bobbins cannot, in practice, be placed readily in line, because of waste lodging within the bobbins or upon the spindles, and because of changes in size of bobbin, owing to atmospheric v ariations.

In this present invention these objections are principally overcome by placing upon the spindle a bobbin-holder, locked thereto so as to remain upon the spindle when the bobbin, shaped to it the holder, is doffed therefrom.

The spindles a may be supported in steps of any usual construction. Above the steps these spindles, carrying bobbin-holders chambered at their lower ends, will be supported by long stationary holsters extended into such chambers, as in the Sawyer plan, and spindles having holders unchambered Will be supported quite near the bottom of the holders by bolsters. The holder b, in Fig. 1, has a truncated head, c, and a chamber, d. Within the chamber, and upon the spindle above the top ofthe bolster which will support the spindie within such chamber, is a holder carrier, made as acollar, c, provided with one or more prongs,2, or projecting surfaces, to enter or engage the substance of the holder, and cause it to rotate with the spindle. The barrel of the holder in Fig. l is shown fitted to the upper portion of the spindle, and at top the spindle is screw-threaded to receive a locking device, made as a tubular nut, 3, by which the holder is prevented from rising upon the spindle as the bobbin f, fitted to the outside of the holder, is doffed.

In Fig. l the bobbin-holder is driven positively with, and practically forms part of, the spindle. The collar e forms a stop by which to gage the lowest position of the holder, and all the holders in a frame may, by reason of such collars, be placedin line. This truncated holder is adapted to receive a bobbin to be Wound with yarn, after the manner of the filling-wind.7 Instead of the head and barrel being plain or smooth, they may be scored or notched in any usual way.

In Fig. 2 the holder is chambered centrally bottom, chambered, carried positively by lugs on a collar, and held down in position on the spindle by a screw and Washer.

Other locking devices than those shown may be used to prevent the holders rising when the bobbins are doffed. Instead of the holder-carrier, one or both sides ofthe spindle might be flattened, to receive against such iattened portion or portions a stud or studs passed through the holder and intersecting its spindle-passage, as in United States Patent No. 134,535.

These holders, instead of being shaped as shown, may be made to conform, as to their external surfaces, with spinning-bobbins of any usual form, and they may be made of wood, rubber, sheet metal, or any other light and suitable material, but preferably wood.

The bobbins maybe made of paper or leather, or both united, or strengthened by cloth, or of fabric stiffened, or of india-rubber, its compounds or substitutes, or of thin metal or wire-gauze, the main object being to make the bobbins light. Preferably these bobbins will be made of paper or leather, in whole or in part. The bobbins are thin shells, made to conform to the shape or outline ofthe holders to which they are applied, in order to be supplied with yarn-loads, and the bobbins and yarn spun and wound thereon may be easily and quickly doied by hand without lifting the holders from the spindles.

This invention, as herein described, makes it possible to dispense withmost of the wooden bobbins now used in spinning on ringframes. In their place are employed the lighter and cheaper bobbins of paper, leather, Ste., which may be quickly fitted to or removed from the holders without jar.

In the use of fine yarn for filling, it is necessary to steam or heat the yarn before weaving it, to reduce the tendency to twist. Yarn spun on wooden bobbins cannot be steamed without spoiling the bobbins; but yarn spun upon the light bobbins described and illustratcd in this present invention may be so steamed without injuring them.

The exible paper, leather, or fibrous bobbins may be handled, with yarn applied, with- .out fear of being broken.

I claim- In a ring-spinning machine, the combination, with the spindle and bobbin-holder and bobbin, substantially as described, ot' a locking device to retain the holder on the spindle when dofng the bobbin, and a holdercarrier to rotate the holder positively With the spindle, all substantially as and for the pur-` poses described. l

In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
